    Notizen: Abstract In-situ floc size measurements were made in suspended matter of the Elbe and Dollard estuaries. Floc size was found to be generally smaller in the surface water than in the bottom water and varied systematically with time in relation to the tidal phase. Maximum floc size was also related to particle concentration and, in the Dollard, probably also to flow on and off the tidal flats. Salinity and the total organic matter content of the suspended matter played a minor or no role. Since flocs break up into uniform size distributions during sampling and analysis, Coulter counter particle size was about constant during the tidal cycle.

    Beschreibung: The hypothesis that the Cape Verde Rise, situated on the lee-side of the Canaries current and being an area of low current velocities, would be a sediment trap, was tested by determining Holocene sedimentation rates on the Rise as well as in the adjacent ocean. The rates were found to vary between 1.9 and 2.6 cm per 1000 years and were not higher on the Rise than in the deeper ocean around it, indicating that under the present conditions of sediment supply, current pattern and bottom configuration the Cape Verde Rise is not a sediment trap. During the Holocene, sedimentation has been rather uniform, consisting of finegrained mineral particles and (organic) carbonate, but during the Würm period also turbidites, large amounts of volcanic minerals and fine quartz of probably eolian origin were deposited. The data on the Würm and Eemian deposits are not sufficient to compare sedimentation rates on the Rise with those in the adjacent ocean. The sedimentation rates found for the Holocene agree well with those found by others in this area.

    Beschreibung: An overview is given of the natural systems of the North Sea: water-circulation, topography and geology of the sea floor, sediment transport, influx of trace constituents (nutrients, trace metals, organic compounds), biological systems and their interrelations. The effects of pollution and other human activities are discussed as well as the difficulties in assessing them where they are obscured by natural changes.
